Several lines of evidence suggest a link between chronic gastritis due to Helicobacter pylori and mucosa-associated lymphoid-tissue (MALT) lymphoma of the stomach.^1,2 A close epidemiologic association has been reported.^3,4,5 The microorganism can be found in the gastric mucosa in nearly all cases, and regression of low-grade gastric MALT lymphoma has been demonstrated after the eradication of H. pylori.^6,7

The suggested progression from H. pylori–associated chronic gastritis to overt MALT lymphoma⁸ has not been formally demonstrated, although if it exists, such a mechanism may have important implications for the treatment of H. pylori–associated gastritis. Each B cell contains immunoglobulin . . . [Full Text of this Article]
